To implement an async MongoDB repository in Python with strict domain separation, use typing.Protocol to define repository ports and the motor driver for infrastructure adapters, ensuring database concerns remain decoupled from domain logic.

The best way to map domain aggregates to BSON documents without leaking driver types is to enforce explicit, manual mapping functions between your domain objects and document structures within the repository adapter layer.

Optimistic concurrency control in a Python motor MongoDB repository uses compare-and-swap (CAS) operations to ensure safe concurrent updates, preventing overwrites by validating document versions during persistence operations.

To scope MongoDB queries per-tenant in a Python domain-driven design architecture, the repository adapter applies standardized tenant-scoping filters to all persistence operations, ensuring strict data isolation for multi-tenant applications.

Yes, this repository pattern supports idempotent index management for document-store persistence by providing standardized startup routines that safely create required indexes without failing on subsequent application restarts.

You should use manual BSON mapping instead of an ORM for Python MongoDB persistence when strict domain-driven design boundaries are required, preventing infrastructure-specific types from leaking into your core domain logic.
